EXP(x)

• where $x$ is the number .

Description

• This function gives the $e$ raised to the power of number.
• In $EXP(x)$, where $x$ represents the exponent of $e$ or $e^{x}$.
• The approximate value of the constant $e=2.718281828459045$ and it is equal to $e^{x}$ or $EXP(1)$.
• It is called the Mathematical Constant or Euler's Number or Napier's Constant.
• It is the base of natural logarithm.
• It can be calculate the sum of infinite series: $e=1+{\frac {1}{1}}+{\frac {1}{1.2}}+{\frac {1}{1.2.3}}+{\frac {1}{1.2.3.4}}+...$
• And the inverse function of the natural logarithm function is the exponential function:

$f^{-1}(x)=e^{x}$.

ZOS

• The syntax is to calculate the EXP in ZOS is $EXP(x)$.
  • where $x$ is the number .
• For e.g.,(-9)..5..2@exp
